Example Embodiment

[0020] The present invention will be further described below in conjunction with the drawings and embodiments:

[0021] Such as figure 1 , 2 The shown fixed bracket for a double-out shaft outer rotor motor includes a shaft sleeve 1 and a plurality of support rods 2 connected to the shaft sleeve 1. Specifically:

[0022] Such as Figure 4 , 5 Shown: the support rod 2 has a connecting head 20, a sleeve matching portion 21 and a connecting tail 22, wherein: the connecting head 20 is provided with a first flange 200 and a connecting hole 3 is opened; on the sleeve matching portion 21 A second flange 210 is provided, and a connecting hole 3 is also opened. The shape of the sleeve matching portion 21 is consistent with the outer circumference of the sleeve 1, and the outer circumference of the sleeve 1 is a circle, so the sleeve matching portion 21 is 1 / n Circumference, n is the number of support rods 2; the connecting tail 22 is provided with a boss 220 protruding outward, the conne...

Abstract

The invention relates to a fixing support for a double-output-shaft external rotor electric motor. The fixing support for the double-output-shaft external rotor electric motor comprises a shaft sleeve and multiple supporting rods, wherein the multiple supporting rods are connected to the shaft sleeve, each supporting rod is provided with a connecting head, a shaft sleeve matching portion and a connecting tail, during connection, the shaft sleeve matching portions are attached to the peripheral surface of the shaft sleeve and are fixedly connected to the peripheral surface of the shaft sleeve, and for every two adjacent supporting rods, the connecting head of one supporting rod is in lap joint with the connecting tail of the other supporting rod and is fixedly connected with the connecting tail of the other supporting rod. According to the fixing support for the double-output-shaft external rotor electric motor, due to the fact that the supporting rods are connected to the shaft sleeve, the defects that according to traditional fixing support obtained through welding, the size is large, the machining difficulty is high, and a larger number of waste materials and excess materials are generated are overcome; the supporting rods can be machined individually and are quite convenient to replace; the strength and rigidity of the whole support are guaranteed due to the mutual connection of the supporting rods, and the overall quality is better.

Description

technical field [0001] The invention relates to the field of general machinery, in particular to a fixed bracket for a double-outlet shaft outer rotor motor. Background technique [0002] The weight of the fan and the motor of the external rotor fan directly acts on the motor bracket. The motor bracket requires great rigidity, torsion resistance and a certain shock absorption capacity. The traditional structure is welded or large sheet metal forming parts, which are large in size and difficult to process. There is a lot of waste left over. In order to overcome the above-mentioned technical problems, in the prior art, there is a structure in which a support rod, a shaft sleeve end cover and a solid rivet are used for connection. The support rod is connected to the shaft sleeve end cover through a solid rivet, but it also has the following disadvantages: the support rod It is connected with the end cover of the shaft sleeve through solid rivets, and the support rod is connect...
